ORNAMENTALLY-ENGRAVED METAL Application filed June 2,

To all whom it may concern:

Be it known that I, EDWARD J. GULIOK, a citizen of the United States,residing at Elkhart, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Improvements in Ornamentally-EngravedMetals and Methods of Producing Same, of which the following is aspecification.

This invention relates to the ornamentation of metal surfaces by the artof engraving. While primarily intended for use in the ornamentation ofmetallic wind musical instruments, such, for instance, as saxophones,and the like, it is capable of more general application.

The invention proceeds upon the principle of applying to the surface ofthe metal object to be ornamented, one or more platings, layers,coatings, or films of material having a color or appearance in suchcontrast with that of the metal of which the body of the object isconstructed, that designs composed of dots, lines, or surfaces ofcontrasting color or appearance may be produced by cutting through oneor more exterior strata and exposing the metal of the body or thematerial of an inner stratum.

pon completion of the design, the entire surface, including thedefinition of the design as well as the ground surrounding the same, issurfaced with a transparent sizing or finish so as to maintain thenatural colors unimpaired; and prior to the application of thisfinishing surface any desired portions of the design or of the groundwork may be treated with pigment or coloring to further developcontrast.

In order that th invention may be fully understood, one method ofrealizing same is disclosed in the accompanying drawings, in which-Figure 1 is a front elevation of a portion of a metal wind musicalinstrument treated in accordance with the invention to develop a designthereon; and

Figure 2 is a section through the metal wall of the object shown inFigure 1 taken on the line 2" x of Figure 1, and drawn on a greatlymagnified scale.

1 represents a thin metal wall to be ornamented, for instance, sheetbrass, 2 is a metallic plating, for instance, silver and AND IvIETEGDQ1" PR-QDUGING 311MB.

therefore contrasting in color with the metal 1, the same being appliedto said wall by any approved method such, for instance, aselectroplating. 3 represents a stratum or layer or lacquer applied tothe plating 2 and embodying in its composition pigment or coloringmatter that contrasts in appearance with both the metal of the wall 1and the plating 2. 4: represents a transparent sizing or finish that isapplied over the surface after the engraving is completed; and 5represents pigment or coloring matter of still another contrasting coloror appearance that may be applied to any of the elements of the design,for instance, flower elements, to lend further character to the design.lhe pigment 5 will be applied preferably before the transparent sizingor finish 4.

As will be seen upon reference to Figure 2, the design can be made up ofa ground work having the color characteristic af-. forded by the surfaceof the lacquer 3, the channels, such as shown at 6, which arecharacterized by the combined effect of the color of the lacquer 8 alongthe sides of the channels, and by the color of the metal plating 2 whichhas been uncovered at the bottoms of the channels; also channels such as7, the appearance of which is characterized along the sides of thechannels by the color of the lacquer 3 and that of the metal plating 2,and at the bottoms of the channels by the color of the metal 1.Similarly, the more extensive recess 8 will be characterized by thecolor of the body metal 1 merging into that of the plating 2 and that ofthe lacquer 3.

The design may be further variegated by applying pigment, such as 5,over some of the petals of the flower form 5.

From the foregoing it will be seen that a metal plate prepared asdescribed can be very highly ornamented by simply cutting through, byany of the processes of etching, engraving, sand-blasting, etc., untildots, lines, grooves, channels, or other recesses are developed with thedesired coloring efi'ect.

As a suitable lacquer'to develop the coating over the electricallydeposited metal plating, I prefer to use known commercial lacquers,consisting of hard drying resinous body with fusel oil, alcohol, etc. asa vehicle.

For the outer transparent finishing coat I prefer to use the finishingmaterial commercially known as izen.

I claim:

The method of ornamenting metal, which consists in applying to thesurface of the metal, platings, coatings, filins or the like, to producea composite material having strata of contrasting appearance, and thencutting through one or more strata of the resuitant piece to discloseunder strata of the composite material on lines conforming to theornamentation to he produced; the resultant surfaces and cuts beingfinished with a transparent sizing; and pigment being 16 applied to someof the surfaces of the design, beneath said sizing.
